Detailed Description

template<class DomainFunction, class RangeFunction = DomainFunction, class LinearOperator = AutomaticDifferenceLinearOperator< DomainFunction, RangeFunction >>
class Dune::Fem::AutomaticDifferenceOperator< DomainFunction, RangeFunction, LinearOperator >

operator providing a Jacobian through automatic differentiation

Note

The Jacobian operator is an on-the-fly operator, i.e., it does not store a matrix but only implements the application.
